GUN-SIGHT.

Specification of Letters Patent.

Patented Sept. 23, 1919.

Application filed January 17, 1918. Serial N 0. 212,309.

To all whom it may concern:

Be it [known that I, WILLIAM ELLIOTT, a citizen of the United States,and a resident of Marshfield, in the county of Coos and State of Oregon,have invented certain new and useful Improvements in Gun-Sights, ofwhich the following is a specification.

My invention is an improvement in gun sights, and has for its object toprovide a fore sight of the character specified, wherein the sightingelement is adjustable vertically with respect to the gun, and whereinthe sight is detachable to permit the use of different types of sights.

In the drawings:

Figure 1 is a partial side view of a gun barrel having the improvedsight;

Fig. 2 is a longitudinal section through the sight;

Fig. 3 is a section on the line 33 of Fig.

Figs. 4, 5 and 6 are front views of different types of sights.

The present embodiment of the invention is shown in connection with agun barrel 1 which has the usual undercut transverse groove 2 forreceiving the undercut base 3 of the sight support 4. This sight supporthas the usual longitudinally extending central rib, which is cut away orreduced at the rear end of the support as indicated at 5, to form avertical shoulder 6 at about the center of the rib, behind which thebead of the sight is mounted.

The sight, shown more particularly in Fig. 4, is mounted in a verticalopening 7 passing through the sight support just in rear of the shoulder6, and the sight has annular grooves 7 which are adapted to be engagedby the holding means to hold the sight in adjusted] position. The sightis movable vertically in the opening 7 and is held in adjusted positionby a transversely arranged pin 8. This pin is mounted to move in atransverse opening 9 in the sight support, and is provided at each endwith a trans versely kerfed head 10 and 11, respectively. The head 10 isof greater diameter than the head 11 and moves in an enlarged portion 12of the opening 9.

A coil spring 13 is arranged between the head and the shoulder formedbetween the body of the bore and the reduced portion, and the springnormally acts to hold the parts in the position of Fig. 3. It will benoticed that the body of the pin is reduced between the spring, and thisreduced portion is tapered. The tapering portion engages the groove 7 ofthe sight, as shown in Figs. 2 and 3, to hold the sight in adjustedposition. By pressing the head 10 inwardly to compress the spring 13,the smallest portion of the tapering portion of the pin may be broughtinto register with the sight opening 6 to release the sight pin topermit it to be raised or lowered, as the case may be. Thus twoadjustments are permitted for the sight shown in Figs. 2 and 4.

In Fig. 5 the sight 13 has three grooves 15 for engagement by the pin,and three adjustments are permitted. *The sight shown in Fig. 16 has twogrooves 17, and has a differently shaped head or bead. Each of the threesight pins shown in Figs. 4, 5 and 6 have differently shaped beads, asshown, and it will be obvious that any form of bead might be provided,and as many adjustments as might be found necessary. When the sights arein adjusted position, the pin 8 firmly holds them in such position, andthe spring 13 prevents accidental displacement of the pin.

I claim:

1. A gun sight comprising a support for attachment to a gun, saidsupport having a longitudinally extending rib cut away at its rear endto form a shoulder at approximately the center of the support, andhaving a vertical opening in rear of the shoulder, a transverse openingintersecting the vertical opening, a sight comprising a pin carrying abead at its upper end and having annular grooves at its lower end in thevertical opening, a pin slidable in the transverse opening for engagingthe groove to hold the sight in adjusted position, a spring normallypressing the pin in one direction, the pin having a head for limitingits movement in the said direction, and the pin having a tapered portionadapted to move into register with the groove to release the sight pinwhen the spring is compressed.

2. A gun sight adapted for attachment to a gun and having a verticalopening intermediate its ends and a transverse opening intersecting thevertical opening, one of a set of interchangeable sights engaging thevertical opening, each comprising a pin having a head at its upper endand annular grooves at its lower end, and a locking pin in thetransverse opening and extending into the vertical opening to engage thegrooves, said pin having a reduced portion annular grooves, a supporthaving a vertical adapted to register With the grooves to reopening forthe pins, and a locking pin lease the sights. movable transversely ofthe said opening and 10 3. A gun sight comprising a support and engagingthe grooves to hold the pins in ad- 5 a series of interchangeable sightmembers justed position.

therefor, each member consisting of a pin having a bead at its upper endand having WILLIAM ELLIOTT.
